How long after a membrane sweep?


I'm 39+0 and just had my first membrane sweep. I'm 3cm dilated and 50% effaced. The sweep wasn't painful at all 🙌 No blood or cramps. Feeling totally normal so far. This is my second pregnancy and I delivered my first child at 39+6 without a sweep.

Wondering how long after a sweep you can expect contractions to start. Thanks!
